Estimate French income tax (impôt sur le revenu) using the 2026 progressive barème and the quotient familial system.
France taxes households, not individuals. Total taxable income is divided by the number of 'parts' (shares) — 1 for a single person, 2 for a married couple — then the brackets apply per-share, and the result is multiplied back by the number of parts. 2026 brackets: 0% to €11,600, 11% to €29,579, 30% to €84,577, 41% to €181,917, 45% above.
